LED-excited emission of opal infiltrated with ferroelectrics and phosphors
摘要：
We have measured emission spectra of opal photonic crystals infiltrated with ferroelectrics and phosphors. At a given excitation wavelength, the emission spectra of the infiltrated opals differ markedly from the spectrum of plain opal: the emission bands are redshifted, and extra peaks are present. The infiltration effect on the emission spectrum of the opal matrix can be accounted for by the shift of the photonic band gap.
